Building and installing a cmxs version of the library about ocamlgraph

[kerneis]

Hmm, in fact that was a stupid request: the proper way to do is for the user of ocamlgraph to link it directly in its own cmxs. There shouldn't be many situations where it makes sense to load ocamlgraph dynamically itself (except maybe to reduce the memory footprint?).

[kerneis]

Maybe it makes sense after all, I'm a bit confused by cmxs I believe. Some sample use here: http://ocsigen.org/ocsigenserver/manual/misc

I'll let you chose wheter you want to close this as invalid or implement it.

Feature granted.
